Having a redundant ADVFS system disk

I currently have two 9 Gb disks available, one to use as a system
disk and the second to use as a hot spare backup.
There are six ADVFS domains on each one, plus a swap partition.
I would like to, once a day via cron job, make copies of these
partitions to the hot spare backup disk.

My questions is the following:

Is there a way to copy the files from the partition on
/dev/rz2a to /dev/rz3a ( and so forth with the other partitions)
in such a way that the ADVFS domain and
file set names are preserved? (preferably with dd).

In other words, I would like to be able, if /dev/rz2 is lost, to swap
/dev/rz3 into its location, and boot my system to see the same
domains and file sets that were there before.

Thanks

Steve Timm
